SENA Serial_IPTM Redirector 4.3 - Manual (Page 39)

Technical Notes on the Auto Detect Feature
The Auto Detect operation uses the following algorithm:
1. A DNS lookup of “wpad” is attempted.
2. For each IP address returned by the DNS lookup, attempt protocol detection for each supported protocol
(SOCKS v5, SOCKS v4, in that order). This is done by attempting a TCP connection to the IANA-defined
port for each protocol, then (if successful) attempting proxy operations.
3. If the DNS lookup came back empty, or if no proxy server protocol has been detected, attempt protocol
detection on each default gateway in the routing table.
4. If no proxy server protocol is detected, the Auto Detect operation is terminated and no settings are
automatically entered.
